Seriously I get tired of having to defend myself from the haters all the time. They then go crying to their mommy when my defense is more brutal than their offense....Simple rule is don't slap me and I won't hit you in the throat....

Quite a stunningly mad car. On the down side, it's the wrong side on the pond. It is difficult to judge from the various videos that are kicking around on the Net actually how good (or bad)this modified Lotus is. It would be good to see this car on a recognised official track, timed, with a comparison against another production vehicle of similar power figures with a professional racing driver at the controls rather than just hooning around canyon roads in the USA.

But you missed the point my car is built for hooning in the twisties not some BS airstrip or a track lap time since I know lap times are first about the driver and then the car... I'm not producing anything for sale this is just my car folks glad to share the build with ya nothing more. If you would like to know what bits broke and what bits didn't break during the build I am more than happy to share the info with ya...As for comparison with other cars of similar power, they can't hoon in the twisties without killing themselves... I have never come across any other car that could hang with me in the canyons and I'm not pushin it..I don't live on a race track or airstrip so times are meaningless.....

But it can pull a tuned liter R1 with great riders without breaking a sweat and it's just a matter of balls as to how fast you really want to go in this rocket pig....

When an Indy Car / Lotus racer comments on the cars performance I listen and there are no need for numbers and lap times when you hear this..

What's the total pressure generated by the twin-charging setup, and how much comes from each charger?

How does the setup avoid turbo lag; does the supercharger somehow redirect to the exhaust to keep the turbo spinning when the throttle is closed?

you over-thinking this...

supercharger is a supercharger, it used the crank to shove air in,

Turbo uses exhaust gas heat/mass to drive it's compressor.

Lag (or more accurately boost threshold) is caused by lack of exhaust gas to drive the turbo

in Franks setup, the engine will be producing reasonably high exhaust gas mass from being supercharged, thus the turbo has more to work with, thus spools up earlier, this then pushes more air into the supercharger, thus more into the engine, thus more exhaust gas, etc etc.

your statement above just shows that you don't understand not just the difference but the causes.

OK, let me rephrase it then. The problem I have with turbocharged engines is the time taken for the feedback loop of exhaust gas and inlet manifold pressure to cause the turbocharger to spool up to full speed when transitioning from closed to open throttle at high revs. The only turbocharged cars I've driven that don't suffer from this are (non-road legal) ones with anti-lag systems that inject un-burnt fuel into the exhaust when the throttle closes to keep the turbo spinning. How does a twin-charger setup get around this problem?

And if that's not "turbo-lag" then what is it called?

I do not care, in any way shape or form, about the point in the rev range at which the turbocharger becomes active at constant throttle, which I believe is called the boost threshold, because I never expect a car to accelerate hard from low revs anyway.
